Specification ofLetters Patent.

Patented Dec. 13, 1910.

Application filed February 8, 1910. Serial No. 541,674.

To all whom it may concern.-

Be it known that I, J AMES MoEvoY, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in an Apparatus for Handling Mine- Cars, of which the following is the specification.

My invention relates to improvements in an apparatus for handling mine cars, and theobject of the invention is to devise a simple means, whereby a mine car may be automatically dumped when it has reached the limit of its movement up the .kick back.

.A further object is to provide means a springbumperlocated at the upper end of the curved portion of the track, swinging spring stops suitably supported on each side .of thecurved portion of the track and de signed to be brought in contact with the wheels by the connections attached to the bumper and operated when the bumper is struck by the car and an end door for the car Cprovided with a closing plunger and lever esigned to co-act with .the inclined projecing an inclined projection located thereon,

tion on the curved side rail, the parts being; arranged and constructed as hereinafter more particularly explained.

larged view of the curved end of the track showing my improvements.

acting with the car. Fig. 5, is an end view ofthe door or flap end of the. car.

In the drawings like letters of reference indicatecorresponding parts inleach figure.

A is the maintrack havin the curved upwardlyextending end A orming what is technically known as the kick back.

B is a switch track extending from a point in proximity to the kick back.

G is a weighing scaleslocated ,atthetop. of thegrade on the main track A (see Fig. l).

D is the mine car, which is shown on the track A at the kick back portion, which is curved upwardly as shown.

I) are the wheels of the car.

E is a rail curved concentrically to the kick back portion of the track and supported on suitable end standards E at one side of the track and in proximity thereto.

1) are the couplers of the car.

F is a spring bumper of any suitable construction and comprising a plunger F having a head F, a sprin F encircling the plunger and a socket F 1nto which the plunger extends.

D is the door or flap at the end of the car, which is swung at the top on the end of the car.

D is a lever and D are plungers connected to the lever and fitting into sockets in the end beam of the car. When the door or flap is closed the end of the lever projects beyond the side of the car and said lever is retained in place by means of a strap D As the car passes up the kick back the lever D comes in contact with the inclined projection E on the rail E and thereby raises the plungersand the door opens of its own gravity and the contents of the car are discharged therefrom gradually as the car proceeds up the kick back. WVhen the car has reached the position for discharge it is necessary to lock the wheels and prevent the car descending before the contents are discharged and for this purpose I provideshoes G located one on each side of the track and swung on rods G held in suitable bearings G and G G is a spiral spring encircling the rod G 1 and having a normal tendency to force the shoes inwardly to engage with the wheel. Each shoe G has an arm Gr attached thereto.

G is a lever fnlcrumed between the tracks and having the opposite ends thereof connected by a wire cord G to the arms G. A spring G connected to one end of the lever normally holds the lever G and the arms Gr in the position shown in Fig. 4, and also the bell crank G connected by the wire cord G to the lever G and the arm G (see Fig. 1) to the bell crank G by the wire cord G and the bell crank G connected to the arm G by the wire cord G all as shown and described.

H are standards located on each side of the track and carrying the sockets H and spring latches H Thelatches H are conlatches H nected by a cord H to the bell cranks H of the bell crank spindle H journaled in suitable bearings H and by arms H to the bumper head F The car after being weighed on the weigh scales C on the main track A has a wheel engage with the bell crank G thereby pulling on the arms G by the connection hereinbefore described and swinging the shoes G located against the wheels of the previous car now on the kick back outwardly, so that they are engaged by the The car now on the kick back is freed and may pass down on to the switch rail B and the car following hereinbefore mentioned of its own gravity will now pass on to the kick back and in doing so the lever D will engage with the raised projection E on the said rail E and open the door and allow of the contents to be deposited. At practically the same time the car comes in contact with the bumper head F and pulls the latches H free from engagement with the shoes G by means of the cord H and connections. The shoes are now thrown by the springs G into contact with the wheels and hold thecar in position while the contents are being dumped.

Although I have described in this specification the apparatus in detail by which the end, which I desire is accomplished, it will, of course, be understood that various alterations or modifications may be made in my invention without departing from the spirit of my invention.

What I claim as my invention is:

1. In an apparatus for handling mine cars, the combination with the main track having a raised portion and a depressed portion and the upwardly curved end forming the kick back, and the switch track, of a stopdesigned to hold the car on the kick back and means operated by the wheel of that car on the main raised portion of the track as it passes toward the kick back for releasing the stop and the car on the'kick back as and for the purpose specified.

2. In an apparatus for handling mine cars, the combination with the main track having a raised portion and a depressed'pon' tion and the upwardly curved end forming the kick back, and the switch track, of shoe stops designed to engage with the wheels of the car to hold the car on the kick back, and means operated by the wheels of that car on the main raised portion of the track as it passes toward the kick back for releasing the stop and the caron the kick back as and for the purpose specified.

3. The combination with the main track having a raised portion and a depressed portion and the upwardly curved end forming the kick back, and the switch track, of shoes swung on rods located in proximity to the track and journaled in suitable bearings,

a springon the rod connected to the shoe.

track and journaled in suitable bearings, a H spring on the rod connected to the shoe and to the bearing, arms connected to the shoes, a lever suitably fulcrumed between the tracks, wire connections to the ends of the lever and the arms, a bell crank on the side of the track, a connection from one end of. the lever to the bell crank, a bell crank located in proximity to the track and the raised portion thereof designed to be operated by the wheels of the car as it passes toward the kick back and a connection between the bell crank on the raised portion of the main track and the bell crank at the kick back as and for the purpose specified.

5. The combination with the main track having a raised portion and a depressed portion and the upwardly curved end forming the kick back, and the switch track, of shoes swung on rods located in proximity to the track and journaled in suitable bearings, a N spring on the rod connected to the shoes and to the bearing, means connected to the shoes and operated by the wheels of the car on the raised portion of the main track for throwing the shoes out as the car on the main portion passes toward the kick back, and means for holding the shoes clear of the wheels of the car when they are thrown back andreleasing means for such means as and for the purpose specified.
